Au is both the chemical abbreviation for gold and an acronym for Actually Useful
This pack adds unique attributes to each piece of gold armor when worn:

• Helmet- shines bright in the dark (persistent night vision)
  
• Chest- the conductivity of the gold attracts items from further away, even when thrown on the ground (item magnetization)
• Leggings- allows the player to swim significantly faster (applies dolphin's grace)
• Boots- adds a spring to your step (2.5 block jump boost)

Instruction file included. Should be multiplayer compatible but not guaranteed, I haven't been able to test it on a server. I'm open to suggestions for improvements.

COMPATIBILITY WARNING
This pack breaks my Hammer datapack if you wear the gold chestplate, BUT there's an easy fix. Simply rename the pack folder (named auarmor-##########) to start with a letter past H (i.e. jauarmor-##########) and both packs will work together again.
